Bird populations under stress

At least 314 species of American birds are expected to lose 50 per cent or more of their range by the end of the century, and have been listed by the Audubon Society as endangered. A United Nations science report says 1 million species of plants and animals are at risk of going extinct. Most at risk are sea birds and grasslands birds, experts say. Birds known as aerial insectivores, like swifts (Apus apus) and nighthawks (Chordeiles minor) , are at risk because the insects they depend on are getting harder to find. One bird, the rufous hummingbird (Selasphorus rufus), is expected to lose all of its range in the United States within this century. And the yellow warbler, which is found across the country and is considered one of the more common birds, has declined by 25 per cent since the 1960s.
